The development of schedule-induced drinking depends on different variables affecting the food delivered at the end of the interfood interval. There are mixed results concerning the effects of varying magnitude and/or preference of different reinforcers in the development of schedule-induced drinking, with some studies showing higher levels and other studies showing lower levels of drinking. The purpose of this study was to observe how differences in preference for a flavor of equally nutritious food pellets influence the development and maintenance of schedule-induced drinking. Using the operant demand framework, four flavors of food pellets were compared to form two groups: one in which subjects would receive their most preferred flavor and another in which subjects would receive their least preferred flavor. In general, licking rates were lower and magazine-entering rates were higher when the preferred flavor was delivered regardless of the fixed-time schedule used. It is suggested that the value of the reinforcer has a larger influence on the immediately preceding behaviors, which will determine the distribution of competing responses in the interreinforcement intervals. These results are relevant to developing public policies that manipulate the taste of healthy food to increase its consumption.
定时诱导饮水的发展取决于影响餐间间隔结束时所提供食物的不同变量。关于不同强化物的不同强度和/或偏好对定时诱导饮水发展的影响，研究结果不一，一些研究显示饮水水平较高，而另一些研究则显示饮水水平较低。本研究的目的是观察对同等营养的食物颗粒口味的偏好差异如何影响定时诱导饮水的发展和维持。使用操作性需求框架，比较了四种口味的食物颗粒，形成两组：一组中，实验对象将获得他们最喜欢的口味；另一组中，实验对象将获得他们最不喜欢的口味。总体而言，无论使用何种固定时间安排，当提供偏好的口味时，舔舐率较低，进入食槽的频率较高。这表明强化物的价值对紧接在前的行为有更大影响，这将决定强化间隔中竞争性反应的分布。这些结果与制定公共政策相关，这些政策可通过操控健康食品的口味来增加其消费量。
